Right. I found the biggest benefit comes from installing reflective front widow shades, window tinting the side windows, installing inserts in the fan holes and building an insulated cover that fits inside the shower bubble. That and installing a circular vent in the A/C cover and my wife making a full curtain across the front of the Axis increased my cooling to heat input by a lot. I went from uncomfortable on a hot day to being able to comfortably cool the living area even in 90 + weather in South Florida. It was a lot cheaper than changing my 13.5k A/c for a 15 and I think I got a lot more comfort. Keeping the heat out is a lot cheaper, easier and better than just increasing your cooling capacity. The circular vent right under the A/C exhaust also allow you to direct the cool air flow directly onto the couch. Closing or redirecting the rest of the vents and closing the bathroom door to the kitchen helps reduce the cooling area. I don’t need to do all this except in really hot weather in the middle of the day. But when you need to - it’s nice to be able to.
